Overview
DTA143ZMFHAT2L is a PNP digital transistor with built-in resistors, designed for surface-mount applications in the VMT3 (SOT-723) package. It features an input resistance of 4.7 kΩ and an emitter-base resistance of 47 kΩ. The device supports a supply voltage of -50V and a collector current of -0.1A. Power dissipation is rated at 0.15W, with a minimum DC current gain (hFE) of 80. It operates within a storage temperature range of -55°C to 150°C and complies with AEC-Q101 automotive standards.
Feature Summary
- Integrates bias resistors to simplify circuit design and reduce component count
- Automotive-grade qualification ensures reliability under harsh operating conditions
- Compact SOT-723 package facilitates high-density PCB layouts
Applications
- Automotive electronic control units requiring robust signal switching
- General-purpose logic level translation in compact devices
- Driver circuits for low-power loads in industrial systems
Procurement Notes
Verify the specific suffix T2L against official RoHM documentation to confirm tape-and-reel specifications and lot traceability. Confirm that the AEC-Q101 qualification status remains active for this specific ordering code, as automotive grades often require strict supply chain controls. Ensure compatibility with existing assembly processes regarding the VMT3 package dimensions.
Selection Notes
Select this component when a PNP configuration with integrated biasing is required for space-constrained designs. The 4.7kΩ input resistor suits standard logic interfaces. Verify that the 0.15W power dissipation rating meets thermal requirements. Consider the VMT3 footprint availability during layout phase. Compare against DTA143Z variants if different packaging or resistance values are needed.
Part Context
The DTA143Z series represents ROHM's standard line of pre-biased transistors. This specific model integrates a PNP BJT with two internal resistors. It belongs to a family optimized for replacing discrete resistor-transistor combinations. The MFHA variant denotes the specific lead frame and molding compound used in the VMT3 package.
Replacement Considerations
DTA143ZU3HZGT106 offers similar electrical characteristics in a standard SOT-323 package. DTA143ZE3HZGTL provides comparable performance in an SOT-416 form factor. Both alternatives maintain the PNP polarity and built-in resistor structure while offering different physical footprints for board redesigns.
